A handling system which carries a carrier carrying a plurality of IC devices, subjects the IC devices to testing, sorts the tested IC devices and stores the tested IC devices, said handling system comprises test units for electrically connecting IC devices to an IC socket for transmitting electrical signals provided by the IC devices to an IC tester; a loader/unloader unit for transferring IC devices to be tested from a container to a carrier, sorting tested IC devices and selectively transferri...

The handling device is particularly suited for handling the test heads on a wafer tester. The test head is thereby supported on a mount which is rotatable about its longitudinal axis on a supporting part. A frame column supports the supporting part adjustably in a vertical direction relative to the frame column via at least one linear bearing. A weight balancing device balances the weight of the head and the mount. The supporting part is configured such that the mount is laterally displayed rela...

A handling robot includes at least four bosses (20a, 20b, 20c, 20d) disposed in a transfer chamber so as to be coaxial with one another and rotatable independently of one another. The bosses are deviated (staggered) in their positions along the axis of a center of rotation. Each of the bosses is provided with an arm (21a, 21b, 21c, 21d), respectively. A link (22a, 22b, 22c, 22d) is coupled to each of the arms, respectively. Two of the bosses which are adjacent to each other in an axial direction...

A handling robot prevents a positioning in a motor unit power transmission system from becoming inaccurate and can eliminate occurrence of vibrations due to a twisting deformation and so forth in the system. The handling robot has an arm fastened to an outside of each of a plurality of ring bosses that are arranged coaxially and turnably. Each of such arms is connected via a link to a carrier table so that turning the ring bosses in mutally opposite directions may cause the carrier table to reci...

The present invention relates to a handling device. The device has an elongated flexible body, a receiving loop, and first and second fastening apparatuses. The elongated flexible body has a first end, a second end, a first terminal end, a top surface, and a bottom surface. The receiving loop is formed at the first end by having the first terminal end securely interconnected to a predetermined position on the elongated flexible body to form an interconnection section on one of the surfaces. The ...

We provide methods and apparatus for handling sod which includes a washing machine in which the water is recycled and during recycling the soil removed from the sod is delivered for reuse. We also provide a method of delivering and take up of rolls of sod in which the peripheral speed of the roll remains constant regardless of the roll diameter; we display methods of physically working sod to remove soil therefrom and also methods of handling sod by supporting it with a flexible mesh where there...

The device further comprises an elongated member which has opposite ends, which is coaxial with the longitudinal axis of the device and which is pivotally mounted inside the sleeve, the opposite ends respectively defining a first end and a second end. The device further comprises at ...

A mobile, self-propelled, multicapability apparatus useful for gripping, lifting, moving, rotating, and otherwise manipulating heavy articles. The inventive apparatus comprises: a base structure; a turret rotatably attached to the base structure; a first boom structure having a first end portion pivotably attached to the turret; a second boom structure having a first end portion pivotably connected to the distal end portion of the first boom structure; a first hydraulic assembly for pivoting the...

A handling apparatus can be used with particular advantage as a pallet moving apparatus, and includes a machine frame with an extension arm, movable in the vertical direction and in the horizontal direction, on which is provided an engaging element for receiving a gripping device. The extension arm has a first rocker element that is mounted on the machine frame and is driven rotatably about a horizontal rotation axis, and at its free end a second rocker element is arranged rotatably and is posit...

In one embodiment, a processor is arranged to handle events. The events handled by the processor have an assigned priority. When a first event is serviced, a first priority mask is generated based on the assigned priority of the first event. The priority mask indicates a set of serviceable events and a set of non-serviceable events and may be written to a priority register. When a second event is received, the priority mask is used to determine whether the second event should preempt the first e...
